OPERATING LOGIC
The DNC-T2003 through DNC-T2032 con-
trols are output sequencers with an ad
justable ON TIME, OFF TIME, and LAST
OUTPUT. Upon application of power to
the L1 and L2 terminals with the high pres-
sure switch co ntacts c losed, the OFF
TIME is initiated. At the end o f the preset
OFF TIME, output 1will turn on for the pre-
set ON TIME. The control will cycle through
all selected outputs until the high and low
pressure switch contacts are opened. If
the pressure switch contacts open dur-
ing the ON TIME, the output will complete
the active ON cycle. The next time the high
pressure switch is closed the next output in
the sequence is fired. Pressure monitoring
with no hysteresis is achieved by using only
a high pressure switch. Placing a jumper
across the high pressure input forces the
control to run continuously.
Note: Controls are shipped with jumper across pressure switch
terminals
PROGRAMMING
Programming is accomplished using 3
buttons: down, up, and select
Down: Decrements the active parameter
Up: Increments the active parameter
Select: Toggles amongst the adjustable
parameters: on-time, off-time, and last
output
Programming Mode Timeout: 60 seconds
TEST & DEFAULT MODES
Test mode is entered by pressing and hold-
ing the select button for 3 seconds while the
unit is in the normal operating mode. Once
in test mode, the display will show tSt.
Pressing the up or down arrow buttons
toggles amongst outputs, and pressing
select pulses the selected output for the
preset ON-TIME. Pressing the select button
while the display shows tSt will change the
display to “dFt”. While the display shows
“dFt”, the up and down arrows toggle
amongst “y”, “n”, and “dFt”. Pressing select
when the message is “y” will set all ad just-
able parameters to the factory defaults. At
any time in test and default modes, pressing
and holding the select button for 1.5 sec-
onds will revert the controller back to the
normal operating mode.
